Patented Aug. 8, 1933 AXLE BEARING@v Victor [alexander Bary, Hendon,London, England Application 28 Claims.

Methods of lubricating axle bearings, vespecially on railroad vehicles,are alreadyk known in which thel lubricant, from a source of supply is,under the rotary action of the axle end or journal, converted into alring of lubricant from which lubricant is then taken and directed tothe places where lubricant is to be applied. It has also been proposedto ut -ice the energy of flow of the rotating ring of lubricant todeliver the lubricant under pressure to the place where it is to beused. The devices for carrying out these methods employ xed parts o1 theaxle bearing for carrying the lubricant into the bearing, while thepresent.

invention has for its object to solve the problem of working the methodin such a way that the lubricant is delivered under pressure directly torotating parts of theaxle bearing, by means of which parts it can beintroduced immediately between the bearing surfaces. It ischaracteristic ofthe invention thatlubricant is converted into a ring oflubricant lrnown manner by the action of' the rotating end and thatlubricant is then pickedup from the rotating lubricant ring, thelubricant so picked up beinfr again subjected to the action of therotating axle end, so that it can bev delivered to the bearing surfacesunder.

a correspondingly high pressure. Axle bearings according to theinvention are characterized by an annular trough rotating with the axleend, into the hollow of which trough there dips a xed leador? duct forthe lubricant, this lead-oli duct cornv municating with the interior ofa receptacle which rotatesv ith the axle end, is uncovered at leastperipherally and is preferably conical. The xed lead-oli duct togetherwith the member for transing shrunk on lto it; this bush may also, atthe same time constitute the splash ring. rThis arrangement affords thepossibility of using again axle ends or journals which by reason or"having been worn and trued up again, have been subviected to a changeor" diameter greater than the maximum; for `nis purpose bushes whichrestore the original strength of the journal are drawn on to thecorrespondingly turned down axle end. It is of the essence of thisinventive conception that it remains independent of the method or"lubrication that may happen to be in use. En order that the axle end maynot be weakened unneceseluly 2 6, i932, Serial No. 524,665, and inGermany duly 3l, 193i;

sarily the duets leading from the hollow chamber oi the receptacle tothe bearing surfaces maybearranged exclusively in the bush and, in aman-- ner already proposed per se, they may open intothe receptaclek inthe vicinity ofthe peripheral uncovering; preferably in they enlargedbase of a iunnelshaped receptacle. n

The drawing illustrates by way of example one constructionaccording tothe idea of the invention. 4

Fig. l is a vertical longitudinal section through a bearing constructedaccording to the invention, while Fig. 2 is a vertical transversesection on line. I- of Fig. 1.

ln both figures l designates the axleend or journal which is stiiened bythe cylindrical bush 2, shrunk -on to it. Supplementary securing meansare aiorded by lixing screws 3. Atv 4 the 2 also forms asplash ring,while its Opposite end face is formed into a conical receptacle 5 hav-ling its wider base turned towards the end of the axle journal androtating with the latter. To the conical receptacle an annular trough 6isrconnected in any. suitable manner. Into the hollow chan'fib'erA 'l ofthe annular trough 6 there dips a iixedlead-oi yduct for the lubricant,this'duct being .secured at 8 tothe casing 9. At 11 this leadofl ducthas a rib which assists in guiding the lubricant to the connecting pipe12. The rib 11 is in themiddle Yof the Yduct 2l formedby the memberllsoi that the ribll acts in the same manner independently ofthe directionof rotation of the trough 6. This connecting pipe opens out ofthedeepest part oi the lead-off duct 10 and is extended intothehollow-chamber 130i the conical receptacle 5. `In the'bush 2 there areprovided either'annular recesses lilfconnected with short transferpassages`l5' or longitudinal passages 16 with short transverse passages17, or bothsystems of passages. i

Between the r.casing 9 and the steel bush 2 is the bearing liner 1Qwhich has Wedge-shaped inlet spaces 22. The axle journal or the bush 2is supported from underneath by a bottom liner 23 which alsor haswedge-*shaped inlet spaces '24. kA supporting member holds up the bottomliner shell from the casing 9 of the bearing. The supporting memberconsists in known manner of l two ywedge-shaped parts, so that bydisplacing the steps 25, formed in the inclined dividing sur- V19 thereto exercise its lubricating function.

axle journal a ring of lubricant is formed in the annular trough 6 fromthe lubricant taken from the supply 18. The lubricant runs down theiixed nose 1G or down the rib 11 thereof as soon as the lead-off duct 10dips into the ring of lubricant. From the lead-off duct 1G the lubricantpasses by Way of the connecting pipe 12 into the hollow chamber 13 ofthe rotating conical receptacle 5. Under the rotary action of theaxle'journal it again assumes an annular form in this receptacle andthus, by reason of the effect of centrifugal force, penetrates to thebearing surfaces between the axle journal 1 and the bearing liner Itreaches the bearing surfaces either by way of the passages 15 and 14 orby Way of the passages 16 and 17 or through both sets of passages.

In place of the lead-of.F duct 10 it is equally satisfactory to use achoke pipe which is extended directly into the hollow chamber 13. It isadvantageous to provide the annular trough 6 with tooth-likeprojections, so that at low speeds of rotation the lubricant actuallydrips off and enters the lead-off duct, which at 21 is formed like atray, by drip feed, from which tray it passes to the hollow chamber 13and thence to the bearing surfaces.
